Novel microorganism for polystyrene biodegradation

Abstract

Disclosed are a composition including a Pseudomonas sp. strain having excellent plastic degradation activity and the use thereof. The Pseudomonas sp. Strain may include Pseudomonas sp. JNU 01 (Accession No: KCTC 14861BP).

What is claimed is: 
     
         1 . A composition for degrading plastic comprising an isolated  Pseudomonas migulae  strain, or a lysate thereof, a culture, a fermentation product, or an extract thereof. 
     
     
         2 . The composition according to  claim 1 , wherein the plastic comprises one or more of polyethylene terephthalate (PET), polyvinyl chloride (PVC), polystyrene (PS), polypropylene (PP) and polyethylene (PE). 
     
     
         3 . The composition according to  claim 1 , wherein the strain is isolated from soil comprising plastic waste. 
     
     
         4 . The composition according to  claim 1 , wherein the strain has polystyrene (PS) degradation activity. 
     
     
         5 . The composition according to  claim 1 , wherein the strain has a 16S rRNA comprising the nucleotide sequence of SEQ ID NO: 1. 
     
     
         6 . The composition according to  claim 1 , wherein the strain is  Pseudomonas  sp. JNU 01. 
     
     
         7 . The composition according to  claim 1 , wherein the strain is  Pseudomonas migulae  JNU 01 (Accession No: KCTC 14861BP). 
     
     
         8 . A microbial agent comprising: a microorganism comprising an isolated  Pseudomonas migulae  strain, a lysate thereof, a culture thereof, a fermentation product thereof, and an extract of the strain, lysate, culture or fermentation product. 
     
     
         9 . The microbial agent according to  claim 8 , wherein the strain is  Pseudomonas  sp. JNU 01. 
     
     
         10 . The microbial agent according to  claim 8 , wherein the strain is  Pseudomonas migulae  JNU01 (Accession No: KCTC 14861BP). 
     
     
         11 . The microbial agent according to  claim 8 , wherein the microbial agent degrades a plastic. 
     
     
         12 . The microbial agent according to  claim 8 , wherein the strain is one isolated from soil including a plastic and the plastic comprises polystyrene. 
     
     
         13 . A method of degrading a plastic comprising using the composition according to  claim 1 , a lysate thereof, a culture thereof, a fermentation product thereof, and an extract of the strain, lysate, culture or fermentation product. 
     
     
         14 . The method according to  claim 13 , wherein the plastic comprises polystyrene. 
     
     
         15 . The method according to  claim 13 , wherein the strain is  Pseudomonas  sp. JNU 01. 
     
     
         16 . The method according to  claim 13 , wherein the strain is  Pseudomonas migulae  JNU 01 (Accession No: KCTC 14861BP).
